very nice

 

What's your Pulley setup?

How much Boost?

Timing @ full boost?

On what Fuel? 93, 100, ect?

 

non rev with a 2.87, 93 octane, 13-16* timing

i think 11.6ish would be very optimistic/impossible for me anyhow. My best is 8.47 in the 1/8th at 89.1mph. If i could chop a 1.79 60's thats a 0.4 seconds right there and prolly 3-4 mph in the 1/8th. OldmanZ is pulling 7.66s @ 93.1 in the 1/8th with a ET of 11.85 @116.7.

I have a long way to go to get that deep in the 7s.

 

Nice power, congrats!

How much Boost with that SI Blower and the 2.87?

 

14-15 psi, but thats irrelevant as its just a measure of my backpressure. I was making 16 psi with 17psi spikes on my old exhaust at 75 less hp.

I figure any of those guys making 400 hp on the 3.12 pulleys, could easily surpass my #'s at much less boost.

 

looks awesome. Good job! Glad to see the Si-trim's really showing their stuff now.

it's even neater that people now understand what cars are capable of hitting 11's even if it's a vortech

 

It's Relevant to the LOAD on the Motor (stock block)

Are you reading that with a gauge or with Software?

 

+1

it's pretty much only irrelevant when comparing vortech psi numbers to turbo psi numbers, but the engine is still seeing that amount of pressure/stress

 

mechanical gauge as well with the gauge on the dyno and also my map sensor. all 3 correlate.

Sharif said it was ok, but that was without back calculating the torque. 400 foot pounds on a DD is alot. Thats 440's on a dynojet.

Maybe he's really trying to push that longblock i keep talking to him about

 

yeah, be careful.

Even 400tq an average dynojet has catastrophically blown up quite a few vortech stock engines.

 

Whatt gotta go home check that dyno sheet! Can not see it from my phone!!

 

No SC'd cars coming to the airstrip event??? Plenty 'o power! Come on out!

 

us SC'd cars know our place. i get my butt kicked enough at the weekly test and tunes for alot less than 175$

 

awww man . A roll on race is way different, esp for a Vortech. Besides, it's only $150. I'll bet you could show us a thing or two. Anyway, it's about being able to let loose and have fun in a relatively safe environment.

 

my fear is that the only thing that will let loose is my conrods

Pretty sure u were on the phone with Sharif when I was there. Are you 2 in cohoots to get me on a built motor: LOL

 

Just checked this thread from my laptop...That's....NICE NUMBER congrat!!!! HOLY!

Edit: makes me wanna upgrade to SI trim...

 

you prolly dont even have to. you are so close with a much bigger pulley. a 2.87 will probably put you at those #'s!

 

I think 370whp seems average. Anyway...i set the schedule with local tuner today, going to get a RETUNE!
I'm shopping for 2.87 pulley with new belt/cog belt ( you know any site i can get it cheap?) What belt size do you using it? no slipping issue?

 

I thought u were running the 34t cog pulley?
